PORTABLE HEATER.

Specification of Letters Patent.

Application filed November 8, 1909. Serial No. 526,766.

Tool]. whom it may concern:

Be it known that we, FRANK B. ELLIS and JAMES L. WVALKER, citizens ofthe United States, and residents of Wharton, in the county of Whartonand State of TeXas, have invented a new and Improved Portable Heater, ofwhich the following is a full, clear, and exact description.

The invention is an improvement in portable heaters and is designed forheating water for toilet and other purposes, or for use as a cookingstove in camping.

The invention has in view heater having all of the essentials forheating water, cooking, etc., inchiding a flask for the fuel, a vesselfor holding the water or food, and

an extra cup or receptacle, all adapted to fit within and be incased bythe body or outer jacket of the heater when the heater is completelyassembled.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure l is a central vertical section of the preferred form of ourimproved heater, on the line 1--1 of Fig. 2; Fig. 2 is a cross sectionof the same on the line 2-9. of Fig. 1; and Fig. 3 is a fragmentarysection of a modified arrangement of the heater.

The invention more specifically described embodies an upright tubularbody or jacket 5, having a suitable handle 6, by which the heater ismoved from place to place. In the lower portion of the heater isslidably received a burner cup 7, having a stand 8, at the centerprovided with a ring support 8 at the top, in which the lower portion ofa burner case 9 fits, the burner case containing coiled therein awire-wrapped wick 10, the wick being exposed through the upper openportion of the case, where it can be ignited.

' The burner cup 7 is provided with air inlet openings 11, to supportthe combustion of the fuel, and is frictionally retained in the 1 lowerportion of the jacket by stamping spring tongues 12, from the sides toprotrude slightly outwardly. The burner cup also'has air inlet openings13' at the bottom, with flattened feet let on the under side, forelevating theppenings 13 above the surface on which the heateris seated.The tubular sup- I port 15' closely fits within the burner cup 7 andprojects above the topedge thereof, as shown in Fig. 3,tl1e supporthaving legs 16 The top of the tubular body or jacket of i the heater isconstructed with a slightly conli'acted mouth, as indicated at '18, andreccives a vessel or cup 19 suitable for heating water, the ,vessel.having a shoulder 20'adapted to seat on the upper edge of'the jacket andconstructed with an outwaidly-pressed head .21 at a point therebelow,adapted to be sprung past the contracted mouth of the body of the heaterwhen the vessel is rcmoved or replaced, this feature of the constructionpreventing the vessel from dropping out .when the heater is tilted topour out the contents. The vessel when in place extends to a pointslightly ahovc'the burner, in which position the water or food placedwithin the vessel is quickly heated, the burner, in the heatingoperation, being withdrawn from the body of the heater until.the loweredge of the latter stands above the inlet openings 11. The burned gasesescape from the. burner through the annular space between theheater-body and vessel, and the outlet openings 22 formed in the upperportion of the heater body.

A cup 23 serves a top for the heater and seats on and closes the top ofthe vessel 19, the cup being frictionally retained in place by aninwardly-proieeting bead 2a stamped in the wall of the vessel.

A flask or pan 25 adapted to contain the alcohol or other liquid fuelfor the burner. is of a size to be contained within the vessel 19, andin event the heater is of a large size for cooking purposes, as whenused as a fea ture of a camper's outfit, the flask may be provided a l.the lower portion with an outlet connection 26, by which it is connectedto the burner, as shown in Fig. 3. The flask is also obviously adaptedto be used as a container for coffee and other liquid food, especiallyin heating the latter within the vessel.

In Fig. l, the tubular support 15 for a pan or similar cooking vessel isremoved, as is preferably the case when the burner is used for heatingthe vessel 19. 7

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. The combination in a'portable heater, 1 selto prevent the vessel from falling out of an upright tubular body, aburner reinovably arranged in the lower portion of the body, a vesselseating on and fitting Within the upper portion of the body, and an iinverted cup serving as a cover for the heater, fitting Within andclosing the upper portion'of the vessel and extending for approximatelyits full depth within the vessel.

2. The combination in a portable heater, of an upright tubular body, aburner carried by the body and arranged at the lower portion thereof, avessel seating on the upper portion of the body and extending therein toa point near the burner, and a cup serving as a top for the heater,seating on and closing the vessel and extending for substantially itsfull depth into the vessel.

3. The combination in a portable heaten, of an upright tubular body, aburner arranged. Within the lower portion of the body,

a cooking vessel seating on and extending into the upper portion of thebody, and beads in connection .with the body and ves- X when the body isinverted and adapted to be sprung past each other.

4. The combination in a portable heater, of an upright tubular bodyhaving an internal shoulder adjacent to its upper edge, a burnerarranged Within the lower portion of the body, and a cooking vesselextending into the upper portion of the body over the burner and havinga shoulder at the top adapted to seat on the upper edge of the body. andhaving a beadadapted to be sprung past the shoulder of the tubular bodyand arranged a substantial distance therebelow when the body and vesselare assembled.

In testimony whereof we have signed our names to this specification inthe presence of twosubscribing Witnesses.
